Your last mail to me is really helpful . I met most of the issues
listed and fixed them as the off-list solution or mine .
Also as the openmpi code changed there are some other issues (almost
the missing function ) that are not reported .For example , the
gettimeofday posix function is not implemented by vxworks library ,I
just wrote a small library for those function. Until now I have
successfully compiled the libopen-rte.a and libopen-pal.a , but now
I stuck
at the problem of fork and exec ,which is not available in the
vxworks. It is not possible to implement the fork and exec by myself.I
have to read through the code using the fork ,then substitute them
with rtpspawn() . It is a challenging work.I really want to know how
Brian Barrett deals with the fork() and exec() .
